Well, I was waiting for a fix for the issue where bypass mode still applies some type of low pass filter to the main speakers which is available here

Somone posted another problem about bypass mode and theater compensation the other day here .

And I just saw this .

I had a couple other interface issues with the 990, but I'm not sure they were firmware bugs, per se. In the end, I sold my 990 a while ago, basically because I got tired of waiting for the first bypass mode fix, which I reported over a year ago.

That's just the kind of stuff I would expect to be fixed. I don't know if they're working on any other issues or changes.
